Oleyl Alcohol Ethoxylate OV-5 is a high-performance non-ionic emulsifier designed for diverse industrial and consumer applications. With a precise ethoxylation degree of 5 moles of ethylene oxide, it excellently balances oil solubility and water compatibility, ensuring stable performance in both aqueous and oil-based formulations.
Its core function is to reduce surface tension, enabling uniform blending of oil and water phases to prevent separation. Boasting high purity (>98%) and GMP-compliant manufacturing, it’s mild (suitable for cosmetics/pharmaceuticals) and low-foaming (ideal for cleaning/lubricants), serving as a reliable choice for multi-field emulsification needs.
Product Advantage
Precise Ethoxylation Degree for Stable Performance
With a strictly controlled ethoxylation degree of 5 moles of ethylene oxide (tested via gas chromatography, accuracy ±0.1 mole), Oleyl Alcohol Ethoxylate OV-5 achieves optimal oil - water balance. This precision ensures consistent emulsifying efficiency—reducing surface tension to 32 - 35 mN/m (measured at 25℃) —enabling long - term stability (≥6 months) in both aqueous and oil - based formulations without phase separation.
High Purity & GMP - Compliant Manufacturing
Produced under ISO 9001 and GMP standards, the product has a purity of over 98% (confirmed by HPLC), with impurities (such as free oleyl alcohol) less than 1.5%. This high purity minimizes irritation (skin irritation test score ≤0.5, in line with FDA 21 CFR Part 172 standards), making it safe for sensitive applications like cosmetics and pharmaceuticals, while avoiding formulation defects caused by impurities.
Multi - Scene Adaptability with Targeted Properties
It has low foam characteristics (foam height ≤15mm after 5 minutes of shaking, tested by Ross - Miles method), which is suitable for cleaning products and industrial lubricants that require low foam to avoid operational interference. At the same time, its good compatibility (can be mixed with anionic, cationic and non - ionic surfactants in any proportion) allows it to be used in paints, food emulsions and other fields, reducing the difficulty of formula development for customers.
Reliable Batch Consistency & Traceability
Each batch of products undergoes 12 quality inspection items (including viscosity, pH, moisture content, etc.), with a batch consistency rate of 99.5% (based on data of 500 + consecutive batches). We provide a complete batch traceability system—each barrel is marked with a unique batch number, which can track raw material sources, production processes and inspection reports, ensuring customers' production safety and regulatory compliance.

Product Uses
Cosmetics & Personal Care
As a mild non-ionic emulsifier, it's added to lotions, creams and shampoos. It blends oil and water phases evenly, enhances product texture and stability, and avoids irritation (meets FDA standards), suitable for sensitive skin formulations.
Industrial Lubricants
Its low-foam property (foam height ≤15mm) makes it ideal for cutting fluids and metalworking fluids. It stabilizes oil-water emulsions, improves lubrication and cooling effects, and reduces equipment wear during processing.
Paints & Coatings
It aids in dispersing pigments and additives in water-based paints. Prevents pigment sedimentation, improves film formation uniformity, and enhances coating adhesion, ensuring consistent product quality across batches.
Food & Pharmaceuticals
With high purity (≥98%) and compliance with EU REACH, it's used in food emulsions (sauces, dairy) and pharmaceutical ointments. It ensures uniform ingredient mixing, maintains product stability, and meets safety standards for human contact.
Cleaning Products
In liquid detergents and industrial cleaners, it boosts oil-stain removal by emulsifying grease. Its low-foam feature avoids foam overflow, making it suitable for high-pressure cleaning systems.
Product Operate Guide
Before use, stir the product gently to ensure uniformity (avoid violent shaking to prevent excess foam). Add it to formulations at 20-40℃ (match base material temp) at 0.5-5% dosage (adjust by application). Mix at 300-500 rpm for 5-10 mins until fully dispersed. Store in a cool, dry place (below 40℃) away from direct sunlight; seal after use to avoid moisture absorption.
FAQ
1、Q: Can the dosage of OV-5 be adjusted beyond 0.5-5%?
A: Yes, but it’s not recommended. The 0.5-5% range balances emulsifying efficiency and cost. Exceeding 5% may cause excess viscosity; below 0.5% may lead to poor phase stability. Test small batches first for adjustments.
2、Q: What if the product solidifies in low-temperature storage?
A: Place the sealed container in a 30-40℃ water bath (avoid direct heating) and stir gently until it returns to a liquid state. This won’t affect its performance.
3、Q: Is OV-5 compatible with acidic or alkaline formulations?
A: It works well in neutral to slightly alkaline (pH 6-9) systems. In strong acid (pH <5) or strong alkali (pH >10) formulations, its emulsifying ability may decrease. Test compatibility before large-scale use.
4、Q: What is the shelf life of OV-5 when stored properly?
A: Under cool, dry, and sealed conditions (below 40℃, away from sunlight), the shelf life is 24 months from the production date. Do not use if it has an unusual odor or discoloration after storage.
